Design Expo demonstration from CHI 2001. A shared node is a packet of information accessible from more than one context. A few techniques exist for display- ing and navigating shared nodes, but they are either not optimal for web environments, or are lacking in richness and ease-of-use. Poly-vectoral reverse navigation (PVRN) is a technique we developed to provide information within a context about other contexts that share a node. From within a shared node, PVRN provides ready navigation to other contexts that share the node. The technique was success- fully used in a commercial web site.
